Enzymology 1

Question 1

What is lock and key theory

Answer 1

enzymes act as a lock and the substrate will act as a key

only the correct substrate will fit into the active site of the enzymes

Question 2

What is induced fit theory?

Answer 2

In this theory substrate play a role in determining the final shape of enzyme and enzymes is partially flexible

only the proper substrate can induce the proper alignment of active site because as the substrate binds, enzymes will then undergo induce-fit, it started to moulded(模具) into precise conformation
